Fred's comment on the probable habits of his registered SEVs when they moved north brought me back to this thread. I knew I had earlier checked out how all mine were doing this winter. I think if this last really cold spell had come before everything had started active growth, then all of my plants would have at least briefly have lost all the green. Since it caught everything in the process of greening up, everything is going to retain some green. With the extra moisture we've received and the mild day temps and lows only in the 40sF, everything will be actively growing again. Anything that doesn't show active growth this week was probably damaged by the freeze. Adapting to this sort of weather pattern will be one of the growing conditions that determine which ones do well here. The other big one will be the summer's frequently excessive dry heat. I think, based on how they have managed so far, that summer will be doable provided they get sufficient moisture. I'm just not sure what they require for increasing and staying healthy yet.
